A load adjustment device for an actuator that determines the power of an internal combustion engine, designed as a throttle valve and is disposed on an actuator shaft in a housing, the actuator shaft being pivotally drivable about the rotary axis of the actuator shaft between a minimal load setting defined by a minimal load stop and a full load setting defined by a full load stop by means of a reversibly drivable actuating drive via an actuating part rotationally fixed to said shaft. The actuator shaft is subject to a load in the minimum load direction by a restoring spring. The actuating part can be subjected to a load by a leg of a torsion spring disposed radially outside the pivoting range of the part, the leg of the torsion spring extending into the pivoting range of the actuating part.
